Alternate Functions of Port D
The Port D pins with alternate functions are shown in
Table 10-8.
The alternate pin configuration is as follows:
• T0/OC.4D/ADC10 – Port D, Bit 7
T0, Timer/Counter0 counter source.
OC.4D: Timer 4 Output Compare D. This pin can be used to generate a high-speed PWM signal
from Timer 4 module. The pin has to be configured as an output (DDD7 set “one”) to serve this
function.
ADC10: Analog to Digital Converter, Channel 10.
• T1/OC.4D/ADC9 – Port D, Bit 6
T1, Timer/Counter1 counter source.
OC.4D: Timer 4 Output Compare D. This pin can be used to generate a high-speed PWM signal
from Timer 4 module, complementary to OC.4D (PD7) signal. The pin has to be configured as
an output (DDD6 set “one”) to serve this function.
ADC9: Analog to Digital Converter, Channel 9
• XCK1/CTS – Port D, Bit 5
XCK1, USART1 External clock. The Data Direction Register (DDD5) controls whether the clock
is output (DDD5 set) or input (DDD5 cleared). The XCK1 pin is active only when the USART1
operates in Synchronous mode.
CTS: Clear-To-Send flow control signal used by enhanced UART module.
• ICP1/ADC8 – Port D, Bit 4
ICP1 – Input Capture Pin 1: The PD4 pin can act as an input capture pin for Timer/Counter1.
ADC8: Analog to Digital Converter, Channel 8
